Great Brython, or Brythoneg Fawr as it is called in Welsh, is a nation that encompasses all of the Brythonic Isles and the peninsula of Brittany. It is a Celtic kingdom, composed of the states of Wales, Ireland, Scotland, England,  and Brittany.

Great Brython is the successor of the Kingdom of Wales, which is now a state within Brython.

The history of Great Brython began before Roman colonization. The Albanic Isles were controlled by Celtic peoples, who all had similar, but still different, cultures. When the Romans arrived, a new group of people, the Britons, emerged to the forefront of Brythonnic society. The Britons pushed the Gaelic people north, and from them came the nations of Scotland and Ireland.

Around the time of the fall of Rome, a new people, the Germanic Angles and Saxons moved into the Albanic Isles, mostly into Brython. The Anglo-Saxons, as they became known as, defeated the Britons, and moved the Britons into the nations of Brittany and Wales. Then, in 1066, a group of Frankish people, the Normans, came from France and conquered the Albanic Isles under William of Normandy. The Norman and Anglo-Saxons formed the basis of the nation of England.

Under English Rule

Under William of Normandy, and his family that ruled after him, England, as the nation was called, grew into a powerful nation in northern Europe. England, however, got into a bloody series of war with France, who claimed Normandy. This led to a bloody struggle, called the Hundred Years War.

France was aided by Scotland to England's north, and even worked to get an independent Welsh state in Brython as early as 1450, when there was a massive revolt. In 1455, the King of Wales, Gavin I "the Restorer" died, and England seized Wales. Five Kings of Wales, from Madoc I to Madoc III ruled in exile from France. Finally, when the King of England died without an heir, the Kingdom broke up, and Wales was freed. Evan II "the Blessed" came from France and reunited the nation of Wales

Welsh Expansion in Brython

Wales quickly began to usurp the land and power of other English successor states. The primary reason was a common heritage and sense of unity, which many states like Mercia, and Northumberland lacked. Wales quickly took over most English states. Scotland was controlled by Scandinavia, and Ireland was ruled independently. Scotland aligned itself with Wales, and ensured Welsh dominance over Brython.

When Scandinavia fell, the Scottish ended the alliance with Wales. This allowed the Dutch and Yorkish people, in 1682,  to declare war on Wales. After ten years, in 1692, the two sides made peace. The Dutch gained the city of London in peace talks, and the Yorkish gained some land around the Yorkish border.

London was given back to Wales after a few years, and in 1697, Scotland and Wales joined into a dynastic union, which hasn't been broken since.

The Welsh, who had a vassal in Ulster, also gained Connacht in the late 1690s. In the First Great War (of 1700), Wales decided to declare war on York and Normandy. They won Brittany in the Treaty of Nantes, and York was vassalized in 1704.

With all of Brython under Welsh control, the Welsh decided to focus on the other Albanic Isle - Ireland. Munster was vasalized in 1704, also. A brief war with Leinster in 1707-1709, allowed the King of Munster to become King of Leinster. Munster and Leinster formed the Kingdom of Cork, while Ulster and Connact formed the Kingdom of Belfast.


The Government of Great Brython is a Parliamentary Kingdom, which is a form of government where the power is shared between two branches - the Emperor of Great Brython (King of Wales and Scotland) and the Great Brythonic Royal Parliament.

History of Government

House of Parliament, Avalon

The system of government is derived from the former government of Wales, which was originally an Absolute Monarchy, but became a Parliamentary Monarchy after influential work by Chancellor Meic Bevan. Bevan believed in a Parliament which could represent the voices of both the wealthy lords and aristocrats and the low- to middle- class people.

In 1717, Bevan's first reform, the institution of a House of Lords, was enacted. King Gavin III, the King who enacted this reform, became immensely popular with his vassals. The House of the People was established in 1718, another of Bevan's reforms.


The States of Great Brython are what make the nation as strong and powerful as it is. Although unified by a Welsh King, it is worth noting that the Kingdom of Great Brython also is made up of the States of Scotland, England, Ireland, and Brittany, in addition to Wales.

Besides the States of Great Brython, there are also Vassal States, Colonies, and Puppet States of the Empire of Great Brython. The vassal states are New South Wales and Hobyo-Somalia, and the puppet states are Morocco and the Welsh Royal Coast.

Each State has its own culture, but most of these cultures are blending into the new Brythonic culture, which is developing from the Welsh, Breton, Gaelic, and English cultures of Brython. One major factor is the recent unification of the States under the Brythonic language.


The military of Wales is a relatively effective fighting force. It is divided into two branches - the Welsh Royal Army and the Welsh Navy. Both branches are headed by equal-ranked Field Marshals, but in times of war they work together quite well.


The military of Wales has fought in the following wars:

  • Great War of 1700 - vs Koori Union, Rome, Normandy, and York- Gained York and Brittany
  • Welsh Invasion of Leinster (1707-1709) - vs Leinster - Gained Leinster
  • Comchellak War of Malagasy Dominance - vs Comchellak and Arabian Federation - Status quo ante bellum
  • Great War of 1720 - vs Orissa and Ethiopia - Gained Brunei and New South Wales
